Variant Group Transformer not working with CLI

[steakscience]

UnoCSS version

0.57.7

Describe the bug

According to this, transformers should work with CLI

However, I can't seem to get variant groups working. Is there something special I need to do?

Reproduction

Something like this wouldn't work when using CLI

System Info

After adding the --write-transformed flag, it does work (but rewrites the original code), even without adding transformers in the UnoCSS config file.

Not sure if that is the intended behavior.

Is it possible to use transformers without using --write-transformed? Ideally, I don't want the original code to be overwritten.
